Bitcoin, the world’s largest cryptocurrency, operates as a fully decentralized and self-sustaining system. It depends on miners and nodes, which are computers running Bitcoin software, to maintain network security. Miners and nodes independently vote on network upgrades, which can involve bug fixes, feature changes, or even network splits referred to as hard forks.
Nevertheless, coordinating upgrades and garnering community consensus within a sprawling blockchain network like Bitcoin can be challenging. This is where Bitcoin Improvement Proposals (BIPs) play a pivotal role. BIPs facilitate organized decision-making within the community regarding protocol adjustments, all without the need for centralized authorities.
So, what precisely are Bitcoin Improvement Proposals (BIPs), and how do they work? These questions will be the focus of our exploration in this article. Let’s begin.
What is a Bitcoin Improvement Proposal (BIP)?
A Bitcoin Improvement Proposal, commonly known as a BIP, is a document that proposes alterations or enhancements to the core Bitcoin blockchain. These proposals can range from overarching community recommendations to substantial protocol adjustments.
Nonetheless, each BIP generally focuses on implementing a singular and significant change to the blockchain. Furthermore, in certain instances, BIPs offer valuable insights to the Bitcoin community and may suggest refinements to the BIP process itself. They involve an array of proposals, including crucial consensus modifications such as protocol upgrades via soft forks and hard forks.
They are also used for adjustments that benefit from collaborative efforts across different versions of the Bitcoin software. These changes could include alterations to how computers communicate or the introduction of new data formats for backup purposes.
Types of BIPs
Bitcoin Improvement Proposals (BIPs) come in three primary categories, each serving a distinct purpose and focusing on specific enhancements. These three BIP categories are as follows:
Standards Track BIPs
Standards Track BIPs are designed to introduce modifications to the Bitcoin network protocol, the methods used for transaction and block validation, and to enhance interoperability among different versions of the Bitcoin protocol, especially in cases of forks.
These BIPs play a pivotal role in upholding the consistency and functionality of the Bitcoin network. Consequently, any proposed changes within standards track BIPs necessitate approval and consensus from the Bitcoin community. This implies significant changes to Bitcoin’s core require the whole community to agree on its terms before implementation.
Informational BIPs
Informational BIPs serve a different purpose. Rather than proposing specific protocol alterations, these BIPs provide valuable resources for sharing knowledge, fostering discussion, and offering insights into various aspects of Bitcoin’s design and operation. Importantly, they do not mandate community consensus for their implementation.
In essence, informational BIPs function as informative references for the Bitcoin community. The community can choose to embrace or disregard their content, as they do not prescribe specific actions or changes.
Process BIPs
Process BIPs propose changes that revolve around modifying Bitcoin’s development procedures and processes, as opposed to its core standards like standard track BIPs.
Unlike standard track BIPs, which directly impact the technical aspects of the Bitcoin protocol, process BIPs have a more administrative or procedural influence. They may suggest adjustments to decision-making processes, how development teams collaborate, or the management of community resources.
Process BIPs also require community consensus, like standards track BIPs for implementation. However, their influence is primarily on the operational aspects surrounding Bitcoin’s development rather than the protocol itself.
How Is a Bitcoin Improvement Proposals (BIPs) Process Created?
A Bitcoin Improvement Proposal (BIP) is created via a structured framework for the Bitcoin community to suggest, deliberate upon, and execute changes or enhancements to the Bitcoin protocol and its ecosystem.
Let’s break down the BIP creation process:
Proposal
The process usually starts when a community member, developer, or group proposes an improvement or change they think would benefit the Bitcoin network. These proposals can cover various ideas, including technical upgrades, changes in user experience, or governance procedures.
Drafting
The individual proposing the change begins by drafting an initial BIP document. This draft provides an exhaustive discussion of the proposed change, covering technical specifications, the rationale behind it, its advantages, and potential risks. Importantly, it must adhere to the BIP format and adhere to established guidelines.
Proposal Discussion
Subsequently, the BIP is shared with the broader Bitcoin community for discussion. These discussions can occur on forums, mailing lists, or other communication platforms frequented by Bitcoin developers and stakeholders. During this phase, community members offer feedback, pose questions, and express their viewpoints on the proposal.
Review
While the discussion is ongoing, the BIP may undergo reviews based on the feedback received from the community. Developers and experts within the Bitcoin ecosystem may also scrutinize the proposal to assess its technical accuracy and feasibility.
Consensus Building
Building consensus within the community is a pivotal step in the process. Gaining support and agreement for the proposal necessitates involvement and endorsement from miners, developers, wallet providers, and stakeholders. Achieving consensus may require time and careful consideration.
Once consensus is reached, the proposal can progress toward implementation, contributing to the ongoing evolution and enhancement of the Bitcoin network and its ecosystem.
How Are BIPs Approved?
Once a Bitcoin Improvement Proposal (BIP) is initially submitted as a draft on the BIP GitHub repository, it undergoes a transparent review and development process. This transparency ensures that anyone interested can monitor its progress and observe the testing outcomes.
Given that the Bitcoin blockchain relies on its underlying code, any proposed changes to the protocol must be reflected in the codebase. Miners must also incorporate a reference to these changes in the blocks they mine, signalling their acceptance or rejection of the proposed implementation.
For instance, let’s take the recent implementation of the Taproot soft fork, known as BIP 341, as an example. The activation of Taproot was expedited using a “speedy trial code” within Bitcoin Core. In the subsequent weeks, a minimum of 90% of mined blocks demonstrated support for the upgrade, indicating strong miner support. This initial backing paved the way for the robust consensus that ultimately led to Taproot’s official approval in November 2021.
A BIP gets approved officially when users, especially node operators, download and use a Bitcoin Core version with the proposed change. Once all upgraded nodes are operational, they can process transactions using the updated protocol. This marks the final step in the approval process for a BIP.
Examples of Past BIP Proposals
BIP 9 (Version Bits)
BIP 9 introduced a mechanism for coordinating and activating soft fork upgrades in Bitcoin. It established a structured method for miners and nodes to indicate their readiness for a change. Notably, it played a pivotal role in implementing the Segregated Witness (SegWit) upgrade in Bitcoin.
BIP 141 (Segregated Witness)
BIP 141 proposed Segregated Witness, a substantial protocol upgrade aimed at improving transactions and supporting second-layer solutions like the Lightning Network. After extensive community discussions, it garnered consensus through the BIP process.
BIP 148 (User Activated Soft Fork)
BIP 148 was a user-activated soft fork proposal crafted to activate Segregated Witness. It ignited significant debate within the community and ultimately led to the adoption of SegWit.
BIP 32 (Hierarchical Deterministic Wallets)
BIP 32 introduced a standardized approach for hierarchical deterministic wallets, greatly enhancing the management of Bitcoin addresses and private keys. This BIP has had a substantial impact on the user experience and the security of Bitcoin wallets.
In each of these instances, the BIP process played a vital role in proposing, deliberating on, and ultimately implementing crucial changes within the Bitcoin network. These BIPs exemplify how this structured approach effectively shapes the evolution of Bitcoin.
In Conclusion
- Bitcoin Improvement Proposals (BIPs) are pivotal in shaping the future of Bitcoin. They provide a clear and organized pathway for suggesting, discussing, and enacting significant modifications to the Bitcoin protocol. With community discussions and consensus-building, Bitcoin can adapt to evolving circumstances.
- In the years ahead, BIPs will continue to be essential for maintaining the integrity and functionality of the Bitcoin network. Bitcoin’s decentralized nature relies on the collective wisdom and collaboration of its community, with BIPs serving as the vehicle for making these shared decisions.
- Through each BIP, Bitcoin advances, adapts, and strengthens its position as a reliable and responsive cryptocurrency in the ever-changing digital landscape.
